Application filed December 6, i905, Serial No. 290,561.

To all whom it may concern;

Be it known that I, EMERY BAYARD, a citiuseful Improvements in Aprons for Shoe Stitching Machines and I do hereby declare the following to be a full, clear, and exact de scription of the invention, suchaswill en- 19 able others skilled in the art to which it'appertains to make and use'the same.

The preser t invention relates to improvements 1n aprons for shoe-stitching machines.

In a shoeestitching machine of the fa miliar curved-needle lock-stitch t e the looper, in moving about the needle to ay the thread in the barbthereof, operates in close proximity to the u perof the shoe which is being stitched, an unless a guard of some kind is' interposed the operator, in-guiding the shoe, will often hold 1t in such a position as to cause it to be struck by the loo er. As the looper is usually moist with o' orwax such an accidental contact soils and damages the shoe when it is of canvas or light colored leather.

One object of the present invention is to produce a guard or apron which will prevent such contact between the work and the in guiding the work. 7 I

Another object of the invention is to produce an apron which will intercept oil or wax looper without inconveniencing the operator thrown from the vibrating take-up to pre;

5 vent soiling of the shoe thereby.

In carrying out this invention the body or main part of the apron is made of thin and stiff sheet metal so as to obtain the necessary strength without substantially reducing the limited space in front of the sewing mechanism which is available for the necessary movements of theshoe in guiding it, while, the upper part of the apron" consists of. a small iece of thin and flexible leather, which is hel in such position in front of the looper as to be inter osed between the looper and tion and Fig. 2 a side elevation of the improved apron, showing the adjacent portions ofa shoe-stitching machine to which it is at- 1 tached, and Fig. 3 is a plan view of'the apron with the flexible portion removed.

The invention is illustrated as applied to a shoe-stitching machine of the t e commonly known as the Goodyear rapi outsole stitcher, provided with an extension-edge at-.

tachment said machine bein with substantial accuracy in t e patent to French and Meyer, No. 473,870; dated April 26,1892. t I

The bod 1 of the apron is made of sheet metal, an is rigidly secured, for convenience, on an upright 2 forming part of the extension-e e attachment, having a slotted lug 3 engage by-a washer 4 and a screw 5 screwed into the upright 2. The body of the apron extends down in front of the take-up 6 of the stitcher. The upper extremity of' thebody lis rovided w1t ears,7 bent inward so asto orm a socket 8 and constitute a holder for the flexible portion of the apron. Inthe socket 8 is held a strip 9 of thin 0' leather or other flexible-material which is located in front of the looper 10 and interposed between the looper and the work. As the holder is located ad'acent to the looper only a small piece of leat er is necessa and it need not be thick and stiff. When 't e u per end of the strip Q is Worn through t 'e stri 'may be reversed and the other end used; until worn out. The strip 9 may be readily removedfor convenience in exchanging 1t or in threading or cleaning the looper, andthe body of the apron need never be removed and may form a permanent fixture.-

Aprons for shoe-stitching machines ha a portion interposed between the looper an the shoe-upper have been used heretofore, but such aprons have always so far-as the inventor is aware, been madeof a single-piece of leather, which, in order to have the necessary stiffness-,must be thick and of good 0 'q uality. @The thickness isobjectionable since it causes the apron .to occupy more-of 0 the'spacie infront of the mechanism, and,

s'ince'the whole apron must be renewed when the upper extrem ty is worn out,such aprons 5 are expensive. andonconvenient.' Havin thus described the invention, what 4 is clai-me isze 1. An apronfor shoestitching machines comprising a holder-.locatedadjacent to th 11:

illustrated v looper, and a removable iece of flexible sheet 'lnaterial held therein between the looper and -the work to revent accidental contact therebetween, su stantial'ly as de scribed.

revent accidental stantially as de 3. An apron for shoe stitching machines comprising a guard of sheet metal located in a removable piece comprising a guard of sheet metal located in front of the take-up and provided with a flexible leather extension located in front of the looper, substantially as described.

5. An apron for shoe stitching machines comprisin in combination with sewing instrumenta ities includin aneedle and an awl operating on opposite si es of the work and a looper located on the awl side of the work, a holder located on the awl side of the work and adjacent to the looper, and a removable piece of flexible sheet material held therein between the looper and the work to prevent accidental contact therebetween, substa'ntially as described.

In testimony whereof I aflix my signature, in presence of two witnesses.
